2. INTRODUCTION
Motherboard is a main
(PCB) printed circuit
board. Where are all the
components or devices
are connected directly
and indirectly
3. TYPES OF MOTHERBOARD
• INTERGRATED MOTHERBOARD
• NON INTEGRATED MOTHERBOARD
• DESKTOP MOTHERBOARD
• LAPTOP MOTHERBOARD
• SERVER MOTHERBOARD
• AT MOTHERBOARD
• ATX MOTHERBOARD
4. TYPES OF MOTHERBOARD BASED
ON DEVICES THEY SUPPORT
• INTEGRATED MOTHERBOARD
• NON INTERGRATED MOTHERBOARD
5. INTERGRATED MOTHERBOARD
An integrated system boards has multiple components integrated
into the board itself. These may include the CPU, video card,
sound card and various controller cards.
6. NON INTEGRATED MOTHERBOARD
• Non Integrated system board uses installable components and
expansion cards. For example, non integrated system board
may allow you to upgrade the video card by removing the old
one and installing a new one. Non integrated motherboard
typically have sever PCI expansion slots as well.
8. AT MOTHERBOARD
An integrated system
board has components
integrated into the board
itself. These may include
the CPU video card,
sound card and various
controller cards.
9. ATX MOTHERBOARD
Advance Technology Extended,
or popularly known as the ATX,
are the motherboard which were
produced by the intel in mind
90’s as an improvement from the
previously working motherboard
such as AT.
11. DESKTOP MOTHERBOARD
• Desktop motherboard are used in personal or desktop
computer. As it is used for application at home and in
office, this type of motherboard is the most basic type.
12. LAPTOP MOTHERBOARD
Laptop motherboard is used to
connect different parts of a
laptop system. These
motherboard generally have
very advanced features as
compared to the desktop
motherboard and most of the
function have been integrated
into the laptop motherboard.
13. SERVER MOTHERBOARD
Server motherboard are
more advanced then
desktop motherboard
and are designed to
offer high-end services
which are more reliable
and ready to operate in
24*7 environments.
14. MANUFACTURES OF
MOTHERBOARD
Motherboard are available in various sizes and
configurations. Some motherboard support 32 and 64 bit
processor as all operating system. It is manufactures by
many companies such as
1. ASUS
2. INTEL
3. MSI
4. Gigabyte.
19. MOTHERBOARD COMPONENTS
• CPU SOCKET
• MEMORY SOCKET/ SLOT
• BIOS RAM
• CMOS
• BATTERY
• CHIPSET
• AGP PORT
• IDE PORT
• SERIAL PORT
• FLOPPY DISK PORT
• I/O CONNECTORS
• MAIN POWER CONNECTOR
• FRONT PANEL CONNECTING PIN
• CPU FAN SOCKET
• NORTH BRIDGE
20. I/O CONNECTORS (PORTS)
• I/O Ports allows communication from an I/o devices
and the motherboard (hence CPU)
21. IDE PORT
Short for Integrated Drive
Electronics, IDE is more
commonly known
as ATA or PATA (parallel ATA).
IDE is different
than SCSI and ESDI (Enhanced
Small Disk Interface) because its
controllers are on each drive,
meaning the drive can connect
directly to the motherboard or
controller
22. SATA PORT
Short for serial AT
attachment, SATA 1.0 was first
released in August 2001 and is a
replacement for the parallel ATA
interface used in IBM compatible
computers. SerialATA is capable of
delivering 1.5 Gbps (approximately
187 MBps) of performance to each drive
within a disk array.
23. USB PORT
Short for universal serial
bus, USB (pronounced yoo-es-bee) is
a plug and play interface that allows a
computer to communicate
with peripheral and other devices.
USB-connected devices cover a
broad range; anything from
keyboards and mice, to music players
and flash drives. For more information
on these devices, see our USB
devices section.
24. BIOS
• Short for Basic Input/Output System, the BIOS (pronounced
bye-oss) is a ROM chip found on motherboards that allows you
to access and set up your computer system at the most basic
level. The picture below is an example of what a BIOS chip may
look like on a computer motherboard. The BIOS pictured is of an
early AMIBIOS, a type of BIOS manufactured by AMI.
25. CMOS
• Alternatively referred to as a RTC (real-time clock), NVRAM (non-volatile
RAM) or CMOS RAM, CMOS is short for complementary metal-oxide
semiconductor. CMOS is an onboard, battery powered semiconductor chip
inside computers that stores information. This information ranges from the
system time and date to system hardware settings for your computer. The
picture shows an example of the most common CMOS coin cell battery
(Panasonic CR 2032 3V) used to power the CMOS memory.
26. EXPANSION SLOT
• Alternatively known as a bus slot or expansion port,
an expansion slot is a connection or port inside
a computer on the motherboard or riser card. It
provides an installation point for a hardware expansion
card to be connected. For example, if you wanted to
install a new video card in the computer, you'd
purchase a video expansion card and install that card
into the compatible expansion slot.
27. COMPUTER EXPANSION SLOTS
Below is a listing of expansion slots commonly found in a computer and the devices
associated with those slots. Clicking any of the links below provide you with additional details.
• AGP - Video card.
• AMR - Modem, sound card.
• CNR - Modem, network card, sound card.
• EISA - SCSI, network card, video card.
• ISA - Network card, sound card, video card.
• PCI - Network card, SCSI, sound card, video card.
• PCI Express - Video card, modem, sound card, network card.
• VESA - Video card.
28. AGP SLOT
Short for accelerated graphics port, AGP is an
advanced port designed for video cards and 3D
accelerators.
29. CNR SLOT
Short for Communication and Network
Riser, CNR is a specification that
supports Audio, Modem, USB,
and LAN interfaces of core logic
chipsets. CNR slot technology was
introduced by Intel on February 7, 2000. It
was mainly developed by leading hardware
and software developers who helped
release the AMR (Audio Modem Riser) slot.
The picture below is an example of a CNR
slot, which is labeled as "CNR_SLOT" on
this motherboard.
30. ISA SLOT
• Short for Industry Standard Architecture, ISA was introduced
by IBM and headed by Mark Dean. ISA was originally an 8-
bit computer bus that was later expanded to a 16-bit bus
in 1984. When this bus was originally released, it was
a proprietary bus, which allowed only IBM to create peripherals
and the actual interface. However, in the early 1980s other
manufacturers were creating the bus.
31. CHIPSET
• Chip set is a set of IC
• The combination of the
North Bridge and South
Bridge in a Computer is
Called the chipset.
32. NORTH BRIDGE
Alternatively referred to as the PAC (PCI/AGP
Controller) and nb, the Northbridge is
an integrated circuit responsible for
communications between
the CPU interface, AGP, and the memory. Unlike
the southbridge, the northbridge is directly
connected to these components. It acts as a
"bridge" for the southbridge chip to communicate
with the CPU, RAM, and graphics controller.
Today, the northbridge is a single-chip that is
north of the PCI bus, however, early computers
may have had up to three separate chips that
made up the northbridge.
33. SOUTH BRIDGE
• The southbridge is an IC on
the motherboard responsible for the hard
drive controller, I/O controller and integrated hardware.
Integrated hardware can include the sound
card and video card if on the
motherboard, USB, PCI, ISA, IDE, BIOS, and Ethernet.
34. SUPER I/O CHIP
• SUPER I/O chip is a single chip which controls
slower I/O Devices which are not controlled by
south bridge
35. MEMORY SOCKET (DIMM SOCKET)
• There are 3 types of memory that currently popular
used in the PC,
1. RD RAM
2. DDR RAM
3. SD RAM
36. CPU SOCKET
• A CPU socket or slot is an electrical
component that attaches to a printed
circuit board (PCB) and is designed to
house a CPU (also called a
microprocessor).
• It is a special type of integrated circuit
socket designed for very high pin counts.
• CPU sockets on the motherboard can
most often be found in most desktop and
server computers, particularly those
based on the Intel x86 architecture
